Solid state fan aka the Frore Systems revolutionary active cooling chip AirJet®

(1/3) > >>

vanarebane:
Hi! As I'm very into efficiently and silently cooling a very power hungry PC (and I like slim powerful devices), I got excited about this new solid state fan, that uses Mems technology to generate quite high air pressure and force air trough slim radiator stack.

Specs for cooling Steam Deck:
Total heat dissipation (@ 85C die temperature, 25C ambient) 10.5 W (net 8.75 W)
Maximum noise inside device at 50 cm 24 dBA
Maximum power consumption 1.75W
Same fan on the Steam Deck is rated for 2.5W

Posting here to see what others think about this product, are you excited or sceptical?

It seems to have the support of Intel and other entities.

I saw this in youtube today. First impression is that this sounds very exciting. I really hope it's true that they have Intel and other manufacturers onboard. Something like this has been needed for a long time. Fans are really annoying in many places.

Marco:
So presumably this is peristaltic?

It's hard to see how the pulsating pressure won't create significant losses, I think this will have to make up for lower efficiency at producing airflow by forcing more turbulent airflow through the fins/pins. Waterblocks can get huge gains through higher turbulence, so I can see that working.

PS. that patent is nondescript to the point I think it should be thrown out, give me a proper preferred embodiment or GTFO. Modern patents are such useless trash.

PPS. oh that's not a Frore patent at all, the article lied to me. This is one of the patents assigned to Frore, interesting that it was actually applied by a German manufacturer of industrial equipment though. Bit weird given the inventor names, I expect all the Indian names more at an US startup than a German manufacturer.

Just saw this on YT. I think it looks quite cool and could be a solution for small notebooks or gaming smartphones in the near future. What I am wondering about is the fact that normal fans also move a lot of air. Is this not an important parameter for cooling? Asking people with knowledge about fluid simulation.
